Baldwin 4'' x 12'' Industrial Cooling Fan 140 CFM 3600 RPM

Baldwin 4'' x 12'' Register Booster

The Baldwin 4'' x 12'' register booster fan delivers 140 CFM airflow at 3600 RPM to push heated or cooled air into rooms that stay too warm or too cold. It fits standard 4 by 12 inch floor, wall or ceiling registers and installs with a flush-mount, drop-in design. Homeowners with uneven temperatures across upstairs bedrooms or distant corners will notice more balanced comfort without forcing the central HVAC system to run longer cycles.

Check Register Size and Power Access

Measure the existing register opening to confirm it matches the 4'' x 12'' dimensions before ordering. The unit requires a nearby standard electrical outlet for its corded-electric power supply. Verify the mounting surface can support a flush installation and that the register grille can be removed for drop-in placement. No ductwork modifications or special wiring are needed.

Quiet Operation with Smart Thermostat

Dual ball-bearing motors keep mechanical noise low enough for bedrooms and nurseries while moving 140 CFM of air. The built-in temperature sensor activates the fan only when the HVAC system is blowing, so power draw stays minimal and the unit never runs idle. A display-off night mode removes LED light, and five speed settings let you match airflow to the room without audible distraction.
